As shown in Figure 5, electrical wiring 2 has the loop-coupled terminal part 22 that is connected electric wire 21 and is configured in the one end that connects electric wire 21 of electricity with vehicle.
Connect electric wire 21 and comprise the isolation layer that there is the electric lead (omitting diagram) of electric conductivity and the surrounding of covering electric lead and there is electrical insulating property.
As shown in Fig. 5 and Fig. 6 (a), the member 225 of remaining silent that terminal part 22 has the caulking part 222 being connected and fixed with the electric lead that is connected electric wire 21, the terminal body 221 arranging from caulking part 222 extensions and links with terminal body 221.
Under the state of caulking part 222 before riveted joint, be roughly cylindric, in week, insertion configures electric lead and caulking part 222 is riveted within it, thereby caulking part 222 is also electrically connected to electric lead crimping.
As shown in Fig. 5 and Fig. 6 (a), from caulking part 222, extend the terminal body 221 setting out and there is a pair of shank 223 arranging to the contrary side extension of the side with disposing caulking part 222.In the forward end of a pair of shank 223, be formed with from each shank 223 outstanding connection protuberance 228 laterally.In addition,, between a pair of shank 223, be formed with the roughly recess 224 of U-shaped.
As shown in Fig. 6 (b), the member 225 of remaining silent becomes roughly rectangular shape, and in four side surfaces 230 that configure abreast with its long side direction one has formed the groove part 229 with circular-arc section shape.In addition, be formed with on the side surface 230 of side surface orthogonal configuration of groove part 229, be formed with the connection recess 231 with the outer shape corresponding with the front end shape of a pair of shank 223.
As shown in Fig. 6 (c), terminal body 221, can be loaded and unloaded both are linked by the front end of a pair of shank 223 is fitted to and is connected recess 231 with parallel member 225.Now, utilize the space being surrounded by terminal body 221 and the member 225 of remaining silent, the through hole 226 that the outer screw section 417 that formation can have for joint 4 inserts.
The storage battery 3 of lift-launch on vehicle thereon surface has two battery posts 31 that are configured to side of the positive electrode electrode and negative side electrode.Battery post 31 becomes the truncated cone shape of distolateral undergauge forward.
As shown in Figure 5 and 7, the joint 4 that is configured in the battery post 31 that is configured to negative side electrode possesses and is fixed on the joint holding part 41 of battery post 31, the assembly department 412 of erection joint holding part 41, the joint linking department 413 that is connected with electrical wiring 2.
Joint holding part 41 forms roughly cylindricly so that rectangular sheet material is roughly configured in to mode on circumference with its long side direction, during from end on observation, has the opening portion 411 in circumference upper shed.
As shown in Figure 5 and 7, in the pair of end portions that is disposed at opening portion 411 of joint holding part 41, possess to radial outside and extend a pair of assembly department 412 arranging and be formed through respectively the bolt-inserting hole 416 in each assembly department 412.
As shown in Figure 5 and 7, joint linking department 413 is from the underpart of the position in a side contrary to assembly department 412 in joint holding part 41, to being formed in the plane vertical with the axial direction of joint holding part 41 and a side contrary with assembly department 412 extended setting.In the substantial middle position of joint holding part 41, dispose with the parallel to an axis of joint linking department 413 erect the outer screw section 417 of setting.
The assembling sequence of the power connection structure 100 of the present embodiment then, is described.
First, joint 4 is assembled on the battery post 31 of the negative side electrode that forms storage battery 3.
In the inner side of joint holding part 41, intert and configure battery post 31, bolt 414 and nut 415 is fastening.When clamping bolt 414 and nut 415, the interval stenosis of opening portion 411 is narrow, and the internal diameter of joint holding part 41 becomes narrow.Thus, joint holding part 41 can be fixed on to battery post 31.
Next, electrical wiring 2 is connected with joint 4.
As shown in Figure 5, the outer screw section 417 that the interspersed configuration in the inner side of the through hole 226 in the terminal part 22 of electrical wiring 2 joint 4 has.Then, by fastening, with instrument, engage with the engagement portion 112 of fastening fixer 1, use the fastening instrument of using, the female thread portion 111 of fastening fixer 1 is carried out to screw thread with the outer screw section 417 of joint 4 and be combined also fastening fixing.Thus, electrical wiring 2 is electrically connected to the battery post 31 that forms the negative side electrode of storage battery 3.
In power connection structure 100, use fastening fixer 1 that the negative side electrode of the storage battery in vehicle 3 is electrically connected to the electrical wiring 2 of vehicle.In vehicle, expectation can be suitably fastening fixing by negative side electrode and electrical wiring 2 when conventionally using, and easily removes fastening fixing in urgency or long-term untapped situation.For this reason, by using fastening fixer 1, can realize the desirable power connection structure 100 that meets above-mentioned requirements.
In addition, as shown in Figure 8, in the power connection structure 100 of present embodiment, in the situation that remove being connected between the battery post 31 of electrical wiring 2 and the negative side electrode of formation storage battery 3, control and rotate the handle part 12 of fastening fixer 1, thereby remove the fixing of terminal part 22.Then, when the layback that electrical wiring 2 is arranged to opposite direction to the extension with shank 223 is dragged, the member 225 of remaining silent of front end that is disposed at shank 223 is separated with terminal part 22.In the terminal part 22 separated with the member 225 of remaining silent, between shank 223, form opening, therefore can extract outer screw section 417 from this.
In power connection structure 100, the terminal part 22 that electrical wiring 2 has has terminal body 221 and the member 225 of remaining silent, this terminal body 221 possesses a pair of shank 223 that is connected with electrical wiring 2 and extends setting to equidirectional, this member 225 of remaining silent is to be configured the front end of a pair of shank 223 mode connected to each other, through hole 226 is formed by terminal body 221 and the space that the member 225 of remaining silent surrounds, and is configured to and the member 225 of remaining silent can be loaded and unloaded from terminal body 221.For this reason, under the state of being combined at the screw thread unclamping between the outer screw section 417 of fastening fixer l and joint 4, remove the link of terminal body 221 and the member 225 of remaining silent, thus can be by outer screw section 417 opening portion 411 of the forward end from a pair of shank 223 of terminal body 221 transfer to.Thus, without fastening fixer l is dismantled completely from outer screw section 417, can be more rapidly and easily remove being connected between negative side electrode and electrical wiring 2.
As mentioned above, according to the power connection structure 100 of present embodiment, can be suitably fastening fixing when conventionally using, easily remove when urgent etc. fastening fixing.
